Description

The DigiRail series comprises a range of Modbus RTU I/O modules designed for industrial automation applications, particularly for integrating analogue or digital signals into supervisory system. These modules are DIN rail mountable and offer RS485 serial communication. They are configured using the free DigiConfig software via Modbus RTU commands. Key features across the series include electrical isolation between inputs and the supply/serial port, LED indicators for communication and status, and a wide operating temperature range of 0 to 70 °C.
